QR code not recognised by iPhone 6 camera in iOS 8.1.2. Will not recognise code as having been scanned and stays on camera screen permanently. 13 missions are active, 6 available. Locale on phone is US, which I can confirm is correct because Apple Pay is active and that only works in US right now. I also have Master Plan installed, but the QR code seems to generate and update without trouble.

I'm having the same issue, but I have less than 10 active missions. It may be irrelevant, but I do have a large number of work orders since I have a level 3 storehouse and level 3 barracks, so I have 36 work orders queued up for my Herb Garden, Mine, Lumber Mill, Barn, Dwarf Bunker, and Alchemy Lab.

Scanning the QR code doesn't work for me.
The scanner stays there, yellow dots appear in the square parts of QR code but nothing happens. The camera tries to focus after a few seconds, things become blurry then come back to readable, yellow dots appear and a few seconds later the cycle starts again.

It looks like the QR codes have issues scanning once you have 10+ missions going at once. I'm not sure if the size of the QR code gets bigger then the app is expecting or what. But my main character often has over 10 missions and it just stops being able to read the QR code for him.

I've recently started using this and have found it extremely useful. When I first downloaded it I thought it was broken and unable to scan, but I think I know what was going on now. It looks like the QR codes have issues scanning once you have 10+ missions going at once. I'm not sure if the size of the QR code gets bigger then the app is expecting or what. But my main character often has over 10 missions and it just stops being able to read the QR code for him. All my other characters work great. And once his number of missions goes down, then he starts working too. From what I can tell, it looks like it's just an amount of information problem. Maybe if there was an option to exclude work orders (cause he has a full set of work orders going as well). Other then that, it's been working great for me.

The app does not seem to catch onto patrol missions. The Nights Watch does not show on the app even though it is in my Garrison Missions list. I am using the most recent app for Android (using it on 5.0.0 / L) and the recent Add-On.

When trying to scan the QR code with my phone (Android 2.3.5), I get a "Found plain text" message, then nothing gets imported into the mobile app. Not sure if this is a problem with the in-game addon or (seems more likely) the mobile app.
